Answer:
3r^3/y^7.
Step-by-step explanation:
9y^-5 / 3y^2r^-3
9 / 3 = 3
y ^-5 / y^2 = y^-7 = 1 / 7y
1 / r^-3 = r^3
So the answer is 3r^3/y^7.

Answer:
The option that no represent a linear function is 
Step-by-step explanation:
we know that
The graph of a linear function is a straight line
The equation of a linear function in slope intercept form is equal to

where
m is the slope
b is the y-intercept
<u><em>Verify each case</em></u>
option 1) we have

This option represent a linear function
where
m=3
b=-2
option 2) we have

This option represent a linear function
where
m=1
b=0
This option represent a linear direct variation function
option 3) we have

This option not represent a linear function
This option represent a exponential function
option 4) we have

This option represent a linear function
where
m=3
b=0
This option represent a linear direct variation function
